Step 1: Define systems
y = 4x - 9
y = x - 3
Step 2: Solve for x
Substitute in y: 4x - 9 = x - 3Subtract x on both sides: 3x - 9 = -3Add 9 to both sides: 3x = 6Divide 3 on both sides: x = 2Step 3: Solve for y
Define: y = x - 3Substitute in x: y = 2 - 3Subtract: y = -1Top Tech adds 55% to the wholesale cost it pays for its inventory. Top Tech bought a wireless mouse for $24. What will be the retail price of the wireless mouse? Round to the nearest penny.
9514 1404 393
Answer:
$37.20
Step-by-step explanation:
Adding 55% to the cost means the cost is multiplied by 1+55% = 1.55.
$24 × 1.55 = $37.20
The retail price will be marked as $37.20.

james went out for a long walk . He walked 3 2/5 of the mile. then he sat down to take rest . After that he walked 5/7 of a mile. how far did he walk together
Answer:
Altogether James walked [tex]4\frac{4}{35}[/tex] miles.
Step-by-step explanation:
The question involves mixed fractions. Mixed fractions are first converted into proper fractions and then any operation can be performed on them.
Given
Distance of first walk = [tex]3\frac{2}{5}[/tex] of a mile
Distance of second walk = 5/7
In order to find how much he walked altogether, we have to find the sum of both fractions.
[tex]Total\ distance = 3\frac{2}{5}+\frac{5}{7}\\= \frac{17}{5}+\frac{5}{7}\\=\frac{17*7}{5*7} + \frac{5*5}{7*5}\\=\frac{119}{35} + \frac{25}{35}\\=\frac{119+25}{35}\\=\frac{144}{35}\\=4\frac{4}{35}[/tex]
Hence,
Altogether James walked [tex]4\frac{4}{35}[/tex] miles.

Write an equation for the line that passes through (- 3, 5) and is parallel to y = - 6x + 1.
Answer:
y-5 = -6(x+3) OR y = -6x-13
Step-by-step explanation:
Let's use slope-intercept form to solve this problem.
Slope intercept form is the following:
y-y1 = m(x-x1)
x1 and y1 are given by the point in the problem.
x1 = -3, y1 = 5.
m is given by the equation in the problem. Lines that are parallel have the same slope. Thus,
m = -6.
If we plug these values into the equation for slope intercept form, we get the following:
y-5 = -6(x-(-3)) which becomes y-5 = -6(x+3)
This is an acceptable answer to the problem. However, point-slope form is also a way it can be written.
y-5 = -6x-18
y = -6x-13

A mini bus can carry 8 students. How many mini buses will be needed to transport 38 students?
Answer:
5 buses
Step-by-step explanation:
you need to divide the number of students (38) by the number of students a mini bus can carry.
38 : 8 = 4.75
since they want to know how many buses will be needed to transport all students, you round 4.75 to 5

Find the equation of a line that passes through the point (2,-5) and is perpendicular to the y-axis. Do not put any spaces in your answer.
Answer:
y=-5
Step-by-step explanation:
Equation of the line
Lines can be expressed in several forms. The slope-intercept form of the line is:
y = mx + b
Where m is the slope of the line and m is the y-intercept.
If the line is perpendicular to the y-axis, then it's a horizontal line. Horizontal lines have slope m=0, thus, the equation is:
y = b
To find the value of b, just substitute the given point:
-5=b
The equation of the line is:
y=-5

An airplane flying with the wind takes 2 hours to travel a distance of 360 miles.
The return trip takes 3 hours flying against the wind.
What is the speed of the airplane in still air and how fast is the wind blowing?
Answer: still air is 150mph. The wind speed is 30mph.
Step-by-step explanation:
X=speed of the plane, Y=speed of the wind.
360/2hours=180
360/3hours=120
2x=180+120
2x=300
X=150
The airplane in still air is 150mph
Add together
X+y=180
150+y=180
Y=180-150
Y=30mph
The wind speed is 30mph

Exercise 3.29. In a school there are four kindergarten classes, with 21, 24, 17 and 28 students. We choose one of the 90 kindergarten students randomly, and denote the number of students in her class by X. Find the expectation and variance of X.
Answer:
Expected mean = 23.2159
Variance = 15.89
Step-by-step explanation:
Given that :
Number of kindergarten students (X) :
21 + 24 + 17 + 28 = 90
P(X):
21/ 90 = 0.233
24/90 = 0.2667
17/90 = 0.1889
28/90 = 0.3111
X : ____ 21 ____24 _____ 17 ______ 28
P(x) : _ 0.233 _ 0.2667 __ 0.1889 __ 0.3111
E(X) = Σ[(p)*p(x)]
(21 * 0.233) + (24 * 0.2667) + (17 * 0.1889) + (28 * 0.3111) = 23.2159
Var(X) : Σ(x²*p(x)) - E(x)²
x² * p(x) = (21^2 * 0.233) + (24^2 * 0.2667) + (17^2 * 0.1889) + (28^2 * 0.3111) - 23.2159^2
554.8667 - 538.97801281
= 15.88868719
= 15.89
